Abstract

The invention discloses a device and a method for detecting head postures based on a monocular camera, and belongs to the field of computer vision. The device for detecting the head posture comprisesan AprilTag label attached to the top of the head of a subject, a monocular camera above the AprilTag label, a notebook computer, a USB transmission line for connecting the monocular camera with the notebook computer, a tripod for fixing the monocular camera, and a telescopic ring for adjusting the height of the tripod. According to the method for detecting the head posture, a monocular camera isused for shooting an AprilTag label attached to the top of the head. The AprilTag label moves along with the head, the spatial pose of the AprilTag label is obtained through the AprilTag algorithm, and the pose of the head is judged through the change of the rotation angle of the AprilTag label. The device and the method are a novel head posture detection method, and the human-computer interactioncapability can be improved.

Description

technical field [0001] The invention belongs to computer vision, and in particular relates to a method and device for detecting head posture based on an AprilTag algorithm combined with a monocular camera and an AprilTag tag. Background technique [0002] With the intelligent development of human-computer interaction and in-depth research in the field of computer vision, head pose recognition, as an important research topic, has attracted more and more people's strong interest in exploring it. At the same time, head gesture recognition has a wide range of application prospects, such as smart wheelchairs, smart monitoring, fatigue detection, games and entertainment and other fields. [0003] The present invention will provide a method based on the AprilTag algorithm, combined with a monocular camera and AprilTag tags to determine the head posture. The device and the method thereof are a novel head posture detection method, which can improve human-computer interaction capabil...
